Install whiteboard in docker-meet-jitsi

According to my server setup I am using jitsi-meet from path (srv/meet/jitsi-meet) and other components of jitsi ( prosody, jicofo and jvb1 and jvb2 ) using docker container as mentioned in docker-compose.yml file. And I commented jitsi-meet code in docker-compose.yml file.

so can you please tell me the steps I should follow to integrate whiteboard.Do I require to run excalidraw front-end separately or not. whiteboard option is not show in more option menu even I enabled the whiteboard in .env file as well as in config.js file of (srv/meet/jitsi-meet).
